`Delta ABC` में सिद्ध कीजिए कि ` sin B + sin C gt sinA`

In a Delta ABC , 2 sinA cos B + 2 sin B cos C + 2 sin C cos A = sin A + sin B + sin C, then Delta ABC is (a) Isoceles (b) Right Angled (c) Acute (d) None of these

In any Delta ABC , prove that a("sin B - sin C")+b("sin C - sinA")+c("sinA - sinB")=0 .

In a Delta ABC , 2 sinA cos B + 2 sin B cos C + 2 sin cos A = sin A + sin B + sin C, then Delta ABC is

In a Delta ABC , 2 sinA cos B + 2 sin B cos C + 2 sin cos A = sin A + sin B + sin C, then Delta ABC is

In Delta ABC, if cos A cos B+ sin A sin B sin C=1 , then a:b:c =

In a Delta ABC " if " a^(2) sin (B - C) + b^(2) sin (C - A) + c^(2) sin (A - B) = 0 , then triangle is

In Delta ABC , sum a (sin B - sin C)
